Styling a sectional can be difficult. Sizing of pillows, what to do in the corner, and what colour palette do I go for are some of the many questions I receive. Here are my recommendations on how to style a sectional. First choose the colour palette. I like to start with the colour of the couch and build from there. I tend to lean more toward a neutral palette and add in one or two pillows with colour. For the examples below I used a mirror effect of matching pillows. You can use this matching look or for more of an eclectic look mix and match all the pillows while keeping the recommended sizes. Option 1: Sofa & Chaise Two Large Square Pillows: 22x22 inch Option 2: Sofa & Chaise Mirror Two Large Square Pillows + Two Smaller Square Pillows 22x22 inch + 20x20 inch Option 3: Sofa & Chaise Asymmetrical Two Large Square Pillows + Two Smaller Square Pillows + One Lumbar on side of extension 22x22 inch + 20x20 inch + 13x20 inch L- Shaped Sectional Three Large Square Pillows + Four Smaller Square Pillows + One Lumbar 22x22 inch + 20x20 inch + 13x20 inch or 14x24 inch
